https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248474 jimp@netgate.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jimp@netgate.com --- Comment #25 from jimp@netgate.com --- The suggested corrections in this issue only solve the problem for a small number of cases. Sacrificing filtering on enc in favor of if_ipsec isn't viable if someone needs both policy-based and route-based IPsec tunnels to different peers at the same time. The number of instances with a mix of both is much larger than instances which are purely using if_ipsec. At least with filtering on enc the firewall can filter traffic for both, just no NAT or per-interface rules. If you disable filtering on enc, if_ipsec rules would work but traffic would flow freely and unfiltered on enc for policy-based tunnels, which is a security risk. The ideal solution would allow both to coexist peacefully rather than being forced to choose. For example, policy-based traffic would filter on enc, while route-based traffic would not be processed by pfil on enc, but would filter on each individual if_ipsec interface instead. Should this issue be reopened, or should there be a new issue framing this as a feature request instead of a bug? -- You are receiving this mail because: You are the assignee for the bug.
